Video scaler with VGA output
To reduce the high likelihood of this project ending in undebuggable disaster, I plan to start off with simple goals and add complexity to the code and input/output circuitry incrementally.
1: Generate a simple 640x480 VGA test pattern with all timing and sync signals controlled by the FPGA. (DONE)
3: Create a framebuffer in Block RAM or the devboard's SRAM.
4: Use the framebuffer to window low resolution (<640x480) digital video input within a 640x480 output frame (no scaling).
5: Attempt to implement scaling algorithms to scale the input resolution to fill the full frame of the output resolution.
6: Add 24-bit color depth to the output with the addition of a THS8134B video DAC.
If I can manage to get this far, I will add additional objectives.
